How do I remove the cervical canal?

In the third trimester of pregnancy, a gynecological examination can be performed to understand the position of the fetal head and the relationship between the ischial spine and whether there is softening or dilation of the cervix at this stage. When the cervical canal does not disappear, the internal examination can understand that the cervical canal is a tubular structure. If the cervical canal is not in good condition, it will feel hard to touch and there is no way to put your fingers into the cervical canal. During regular uterine contractions, the cervical canal may soften, dilate, or disappear gradually. During the internal examination, no tubular structure of the cervical canal can be clearly felt, and it is easy to feel whether there is any enlargement of the cervical opening.
